Abstract
A polyester resin composition for profile extrusion molding comprising an amorphous polyester, at least one component selected from the group consisting of a crystalline polyester and a nucleating agent, and optionally a reactive compound; a polyester resin composition for profile extrusion molding comprising a polyester resin, and a reactive compound having a weight average molecular weight of 200 to 500,000; and a profile shape comprising a resin having a reduced viscosity ratio of 1.01 to 3.00, a reduced viscosity ratio being a ratio of a reduced viscosity of a resin after molding to that of a resin before molding. They do not suffer from sagging in the molding process, they improve the shape accuracy at corners and edges of profile shapes from a die to a sizing step and also resistance to whitening on bending in transparent products, and can provide profile shapes having good solvent resistance and detergent resistance.
